The BBC says:
Climate change is to blame for a drop in the number of some birds that visit Britain each winter, the RSPB says.
The charity said many wildfowl no longer needed to migrate as far as the UK from places like Greenland and Siberia because of warmer winters.
Numbers of seven regular visitors, including the shelduck, mallard and turnstone, are declining, it warned.
But the overall number of waterbirds wintering in the UK has doubled since the late 1970s, a report adds.
The State of the UK's Birds 2006 report, says in particular the number of wading birds including the black-tailed godwit and the avocet, had increased markedly, mainly due to action by conservationists.
Interesting that the RSPB claims that the lack of certain birds is all down to climate change, but the doubling of birds overall is all down to those brilliant conservationists. This is a bit too convenient a story. The zones of all birds should be getting pushed northwards, so if some birds are getting pushed off the top, some other birds should be entering from the bottom. And should anyone be that concerned that some birds are getting pushed off the top (as long as they are surviving above that)? The BBC of course uses the alarmist word "warned", since according to the BBC (and the RSPB) the end of the world is near.
